Abstract: 257,243. British Thomson-Houston Co., Ltd., (Assignees of Davey, W. P.). Aug. 24, 1925, [Convention date]. Emulsions, making.- In coating-compositions comprising a water emulsion of ingredients which harden on heating and including rubber, a loading material such as lampblack or clay is added, in such proportions as to prevent scumming of the rubber droplets. The invention may be applied to water japans of the type described in Specification 121,533 and comprising a pitchy material such as gilsonite, an oleaginous material such as linseed oil with or without colouring or modifying ingredients, emulsified in water, with which rubber has been incorporated either by incorporation with the base, or by the addition to the emulsion of latex. Suitable proportions of a material such as lamp black or clay, having a greater density than water, is added, to weight the droplets. In an example a mixture of 85 lbs. each of oxidized linseed and china wood oils, 50 lbs. of rubber, 10 lbs. of lamp black and 10 lbs. of sodium carbonate is heated until dispersion ensues. Asphaltic material such as 150 lbs. of gilsonite and other materials such as 10 lbs. of resin and 5 1bs. of sulphur are added and heating continued. Boiling water is finally added as described in Specification 212,248. Alternatively, instead of mixing the rubber with the oils, rubber latex containing lamp-black or other loading agent in dispersion, may be added to the other materials when they are emulsified. The Specification as open to inspection under Sect. 91 (3) (a) claims also emulsions comprising one or more disperse components heavier than the dispersion medium and one or more lighter than it, the components being so proportioned that the disperse phase has practically the same density as the dispersion medium. These claims do not appear in the Specification as accepted.

Title: Improvements in alternating current signal receivers
IPC: H04Q1/446
Filed: 1933-07-05
Abstract: 420,387. Automatic exchange systems. RYALL, L. E., 52, Crescent Gardens, Eastcote, Ruislip, Middlesex. July 5, 1933, No. 19105. [Class 40 (iv)] [See also Group XL] An A.C. signal receiver, e.g. for responding to numerical impulses in a telephone system, comprises a selective network over which signals of a particular frequency are passed to a rectifier which is biassed by rectified signals derived from the input side of the network through an untuned circuit and is thereby rendered ineffective when signals of other frequencies are received. The rectifier may be of the dry plate type or a thermionic diode or triode. In the latter case the bias derived from the unwanted signal may be made to make the grid more negative so as to suppress the anode current or more positive so as to make the valve act as an amplifier instead of a rectifier. The circuit shown is for dealing with 500 cycle signals modulated or interrupted at 20 cycles. In the absence of other frequencies a certain proportion of the signal is rectified at 10 and produces a biassing voltage across the condenser 11 which is not sufficient to prevent the actuation of relay 9 by signals passing through the selective network 4 to the rectifier 7. When however other frequencies are received, the biassing voltage is larger that that of the fraction of the A.C. passing the selective network and the relay 9 is unaffected. The invention is applicable in systems in which the wanted signal is not interrupted or modulated but in this case the bias voltage on 11 must not change the anode current in the same direction as a normal signal.
